GUYING-POLE.

To all whom it may concern:

Be it known that we, FREDERICK G. SHULL and ELON J. DE RIGHT, citizens of the United States, residing at Concord, county of Middlesex, Commonwealth of Massachusetts, and Kansas City, county of Jackson, State of Missouri, respectively, have invented certain new and useful Improvements in Guying-Poles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enables others skilled in the art to which it appertains to make and use the same. 7

The present invention relates to means for supporting and guying poles and more particularlyto devices of this character employed. for guying poles which carry wires and cables.

It is customary to brace and su port this type of pole through a guy extending diagonally from the pole to the ground and having its ends secured by some form of clamp which is intended to prevent slackening'of the guy wire. The form of clamp most genbeen set up and the guy wire initially erally em loyed is made in two pieces between wh1ch the length of the guy wire and the free end pass and are clamped in place by several b0lts, the number depending upon the size of the guy wire and the strain imposed thereon. This typeof clamp is unsatisfactory as it is expensive to manufacture, does not absolutely insure against slackening of the guywire, and does not facilitate the removal of the guy wire when so deopposite ends of the guy .w1re' are looped' through suitable connecting members and sired. A number of clamps have been devised intended to overcome .the disadvantages of the bolt type of clamp above de-,

scribed, but all of these .constructions are expensive and ineflicient, and with the exception of the bolt clamp, none of them have [gone into extensive use.

One object of the present invention is to provide improved means for guying and bracing a post which isinexpensive to manufacture and may be readily assembled when setting up the post to put the requisite tension upon the guy wire.v

A further object of the invention is 'to' provide an improved form f clamp for a guy wire which insures against any slackemng of the guy wire a er the post has P in tension but which may be easil disconnected' from the guy wire when esired to Specification of Letters fatent.

Application med August 27, 1917. Serial No. 188,372.

Patented Feb. 19, 1918.

Figure 1 represents an elevation of a pole.

having the improved guying means attached thereto; Fig. 2 is a detail illustrating a side elevation of the improved clamp with the guy wire passing therethrough; Fig: 3 is a" top plan view of the clamp shown in Fig. 2; Fig. 4 is a detail showing a cross section upon the line 4-4 of Fig. 3; Fi 5 is a,

cross section upon the line 55 0 Fig. 3; Fig. 6 is a crosssection upon the line 6-6 of Fig. 3; and Fig. 7 is a cross section upon the line 77 of Fig. 3 showing the detachable connection between the lug and base of the clamp.

In the illustrated embodiment of the inventipn a telephone or electric light pole is indicated at 1, having cross arms 2 which carry the usual insulators 3. This'pole is braced by a guy wire indicated generally at '5', and extending diagonally from a point between the two cross arms to the ground, asshown clearly in Fig. 1.-

According to the present invention the the free end of the loop is clamped in each case to the length of the guy wire by an improved form of clamp which providesforv guy wire, 1n position afterthe initial tension has been put thereon. Upon referring to v Fig. 1 it will be noted that the upper endv of the guy wire is passed through the eye 10 of a bolt 11 which passes through the pole land is secured at 1ts opposite end by a nut 12. The opposite or lower end of the :guy wire is connected to a suitable. anchor-,

ing device 15 embedded in the ground and provided with an eye bolt 16 through which is passed a-suitably shaped thimble 17 connected directly to the guy wire clamp.

The free end of the guy wire is clamped to Q the length of the wire by a simple and eificient form of clamp which permits an initial adjustment of the wire to take up slack and positively locks the wire immediately upon the removal of the slack and the placing of the wire under tension. To this end a clamp 20 is designed for the reception of opposite sides of the loop of guy wire, the clamp having a base portion 21 upon which the wire rests and projecting lugs 22, 23 and 24 about which opposite sides of the bight of wire pass, as will be more fully described hereinafter. The length 25 of the guy wire forming one side of the bight passes into the clamp at the right of the lug 22, next passes about the left side of the. lug 23, and finally about the right side of the lug 24, from which it passes to the pole, as shown clearly in Fig. 3. The free end 26 forming the opposite side of'the bight enters the clamp at the left side of the lug 24, then passes be-- neath the length of the wire about the right side of the lug 23, again beneath the length of the wire, and finally extends out of the clamp at the left side of the lug 22. This construction causes the length 25 of the guy wire to bind-upon the free end 26 of the wire atthe two points of intersection 27 and 28 when the guy wire is put in tension. With this construction in order to initially put tension on the guy wire it is only necessary to pull upon the free end 26 which is permitted to reeve freely through the clamp until the slack is completely taken out of the wire, when the length 25 of the wire binds upon the free end at the points of intersection 27 and 28, preventing not only further movementof the latter 'to tighten the guy wire, but in addition locking the free end of the wire in place to prevent any subsequent slackenin of the guy wire. In order to augment t e gripping effect of ,.0ne

side of the bight of wire upon the other each of the lugs 22,. 23 and 24 is provided with a cam face 30 shaped in accordance with the particular size and shape of the guy wire to force the guy wire passing thereabout into the junction of the lug with the base portion 21 ofthe clamp. The advantages of this construction will be readily apparent from an inspection of the drawings where it willbe observed that the greater the strain upon the 'guy wire the greater the tendency vto press the length 25 of the wire against the free end 26. In order to prevent the pressure of the upper length of wire fromflatt'ening out the under length of wire at the points of intersection and in consequence impairing the strength of the wire, the base 21 of the clamp is provided, as shown clearly .in the drawings, with a shallow groove 32 extending between the lugs 'and adapted for the reception of the free end 26 of the wire, which is clamped between the length of the wire and the base. This recess or groove is clamping action of the upper length of wire 25 but is of sufficient depth to aid the free end ofthe wire in retaining its shape, preventing separation of the strands and consequent weakening of the wire. From an inspection of Figs- 1 and ,3 of the drawings it will be noted that the lug 22 is slightly offset from the center line of the clamp so that the length 25 of the wire passes from the lug 23 to the lug 22, and thence off of the clamp without abrupt bends. In the construction shown in the drawings both the npperand lower clamps are substantially identical except that the lower clamp is provided with a tail piece 33 having an opening adapted to receive the bolt 34 of the'thimble 17. In assembling the guy wire with the upper clamp, a ring 37 is conveniently slipped over the bight of wire between the pole and the clamp, as shown in Fig. 1, and serves to hold the opposite sides of the bight in contact with the lug 24, thus increasing the efiiciency of the clamp.-

It will be obvious to those skilled in the sion from the wire. In order to permit theconvenient removal of the guy wire from the pole, means are provided for relieving the pressure of the upper side of the loop of wire upon the lower side and to this end the lug 23 is made as an independent member detachably connected to the base 21.

The lug is provided with a V-shaped tongue 28 projecting from the bottom of the lug and adapted to be received-in a corresponding groove 40 extending lengthwise of a boss 41 formed upon the base. The closedat both ends by the boss and the cooperated tongue and groove thus position the lug both laterally and longitudinally with relation to the base. through the lug and baseand is secured in place by the usual form of clamping nut 43 engaging with the bottom of the base. With this construction the guy wire is normally locked in the clamp after the initial assembling but the subsequent-removal of the wire is conveniently accomplished by groove 40 is A bolt 42 passes detaching the lug from the clamp. This immemes shown and described, it will be understood that this construction and arran ement is not essential except so far as speci ed in the claims, and may be changed or modified without departing from the broader features of the invention.
